What does the term 'elasticity' refer to in Cloud RAN architecture?

The term 'elasticity' in Cloud RAN architecture refers to the capacity for rapid scaling of resources. This characteristic is essential in cloud environments, where demand for network capacity can fluctuate significantly. Elasticity allows the network to dynamically adjust its resource allocation—both up and down—to meet changing traffic conditions and user demands.

In practical terms, when there is a surge in traffic, resources such as processing power or bandwidth can be quickly increased to maintain optimal performance without degradation of service. Conversely, during periods of lower demand, the system can scale back resources to minimize costs and increase efficiency. This versatility is one of the significant advantages of cloud-based architectures compared to traditional, rigid network systems.
